Instructions for Preparing and Using Glow Powder in Printing Paste

Product Introduction

This product is made with iSuoChem's special glow pigment and a clear printing paste. The glow material stores light energy when exposed to light and slowly releases it in the dark. Using screen printing, you can print glow designs on fabrics and non-woven materials. Tests show that these prints can stand up to rubbing, washing, sun, and sweat. The product is safe, eco-friendly, and free from any harmful or radioactive substances.

A key feature of this product is that it only needs 10–30 minutes in sunlight or under a light to glow in the dark for over 12 hours. The glow starts bright and slowly becomes less bright over time. It can be recharged again and again by light, and lasts for more than 5 years.

Product Uses

Patterns made with this product look normal during the day and glow at night, creating a unique and eye-catching effect. It can be used on clothing, shoes, bags, home fabrics, and signs. It works especially well for:

• Safety workwear (for cleaners, firefighters, etc.)

• Kids' clothes and school items

• Home decoration fabrics

• Outdoor sports gear

• Promotional and advertising materials

As more people learn about this product, its uses keep growing.

How to Prepare the Printing Paste

1. Choosing the Glow Powder

We suggest using our water-based glow powder. It comes in different Particle sizes:

Bigger Particles glow brighter but do not print as clearly.

2. Mixing the Printing Paste

Use a neutral or slightly alkaline clear printing paste (pH 7–9 works best). Add glow powder by weight, mix well at low speed (300–500 rpm is best). If it's too thick, add thinner to get the right consistency.

Mixing Ratios to Try:

Helpful Tip: Print a layer of white paste first before printing the glow layer. This makes the glow much brighter because the white reflects more light.

3. Printing Pastes We Suggest

You can use:

• Nylon paste

• High-quality clear paste from Japan

• Stretchable clear paste from Japan

• Shiny paste from Hong Kong

Important Tips for Use

• Screen Mesh: Use 100–120 mesh screens. Too open a mesh will let too much paste through; too fine a mesh can block the glow effect.

• Print Thickness: Print at 0.2–0.3 mm thickness. Thinner prints will not glow as brightly.

• Drying: Let it air dry or dry at low heat (80–100°C). Do not use high heat.

• Curing: Heat at 130–150°C for 3–5 minutes for best results.

Friendly Reminder: Mix only what you need and use it right away. Do not store mixed paste for long. Keep unused paste in a sealed container and use within 24 hours.

Keeping the Glow Strong

To help the print keep glowing well over time:

• Let it get plenty of light often.

• Do not leave it in strong direct sun for too long.

• Wash with mild soap.

• Do not use bleach.
